| General information |
|---|
Iscaguard BSB is compatible with most personal care ingredients. In aqueous formulations, heating to 40°C may be required to fully dissolve the preservative. However, prolonged exposure to high temperatures should be avoided in order to protect against discolouration. Iscaguard BSB works effectively at pH values below 6.5, though for optimal efficacy we recommend that the pH of the finished product is less than 6. |
